The current Transform in vtkCamera is computed as: Transform = UserTransformPerspectiveTransformViewTransform

To me this does not make any sense. For what I would like to do (controlling camera position and orientation by an external transform), this would make more sense:

Transform = PerspectiveTransformUserTransformViewTransform

This can be achived by moving the concatenate code in ComputePerspectiveTransform to the end of the function.

Also, when using the UserTransform this way the camera light will not follow, since it only depends on the ViewTransform. Unless the UserTransform is intended for an entierly different use, it would be nice to have the camera light transform depend on UserTransform*ViewTransform.
